It is understood that the company's polypropylene unit extrusion machine was originally a German Siemens unit integrated control system. After the on-site integrated explosion-proof operating station failed, the start-up, shutdown and daily parameter adjustment of the extruder could not be realized on-site real-time monitoring and operation. The supply cycle was long and the price was high. It only cost 830,000 yuan to integrate imported spare parts. The technical team of the center initiated special technical research, conducted in-depth analysis and research on the communication methods and operating principles of the original data collection station, and formulated a scientific, rigorous and meticulous domestic alternative technology transformation plan. In order to repair the on-site data collection station as soon as possible, the center prepared hardware equipment such as touch screens, switches, and explosion-proof control cabinets, tested network compatibility, modified the operating system and network parameters, and tested the matching of the system and the collection station. After sufficient feasibility testing, the hardware installation and software deployment were completed during the shutdown and emergency repair period, and the reconstructed and repaired on-site operation station was put into normal use. The investment in this technical transformation was 39,000 yuan. The technology of remote desktop access to the operation station in the cabinet room was used to replace the original integrated operation station on site, achieving the same functions. It not only avoided the risk of poor connection of the start-up process caused by the delay of remote operation signals in the control room, but also realized the localization of spare parts, reduced costs and increased efficiency, and autonomous operations, creating new value for the enterprise.
